WebMWD :: Key Seismic MWD We have developed a model-based water-layer demultiple (MWD) technique specifically designed to attenuate multiples in shallow water. This technique is similar to Surface Related Multiple Elimination (SRME) which has become the de facto standard for marine demultiple. WebSep 1, 2024 · In this abstract, we propose to use 3D continuous wavelet transform (CWT) to denoise pre-stack seismic data. We first decompose a 3D pre-stack volume to a six-dimensional domain including the space coordinates b= ( bx,by,bz) T, scalar a, dip θ and azimuth ϕ, which can access to the 3D spatial information.
